I recently wrote about the really nice tripod that I put together, but I didn't talk much about how I arrived at the mix of components I got, nor about how I'll use them.
Those are just the most very basic issues (there are plenty more), but one thing these points have in common is that, generally speaking, the more you optimize for them, the less stable (more shaky) the tripod becomes. And lest we forget, stability is the whole point of using a tripod in the first place, which is why it's so difficult to put together a good one without compromising.
I'm no expert on tripods, so I'm sure that there are plenty more things that I should be listing.
Most or all of these sets of points come into play with each component. For example, I opted for a tall set of legs (Gitzo 3540XLS) because I'm sort of tall myself, but in doing so I gave up the ability to pack it in all but my largest suitcase (and even at that, I have to disassemble it to get it in there). Also, its size makes it trouble enough to carry around without having the added hassle of it being really heavy, so I had to spend more to get a lower-weight (yet still stable) material.
If you have a center column, does using it reduce stability enough to matter?
How important is it to use a remote shutter release?
How important is using mirror lock up?
Should you use your lens' image stabilization?
Should you hang weight from the tripod to add stability?
How much stability do you lose by extending all the tripod leg sections?
I don't know how to answer these questions myself, but I want to. My next post, Tripod Stability Tests, Part I, looks into the tests I've done to try to find out.
